Symptoms

Failure to consume adequate amounts of nutrients can lead to noticeable and measurable physical changes that are symptoms of deficiency disease.

Explanation:

Deficiency diseases are identified by certain symptons that can be discovered by physical examination such as:

- bleeding gums, in the case of scurvy (vitamin C deficiency)

- inability to see at night or in dark areas, as in the case of Night-blindness (Vitamin A deficiency)

- weak bones, as in the case of rickets (vitamin D deficiency).

Thus, symptoms are the changes that are associated with deficiency disease, and are easily noticed and measured.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
